论经济法的调整对象范围

关于经济法的调整对象历来是经济法学甚至包括民法学、行政法学界争执的一个焦点,但是大家还是就经济法的基本理念达成了共识,即经济法是国家干预市场经济的基本法律形式,鉴于我国完全不同于西方的市场进化模式,当前我国国家干预市场的范围应当严格限定,干预市场与培育市场应当两种手段并存.经济法以社会公共利益为本位的法益追求是经济法区别于传统的公法和私法独立存在的根本理由.在此基础上再界定经济法的调整对象也就不再困难.     

反屠王:对辽代再生仪的重新解读

詹·弗雷泽在<金枝>中展示了远古人类普遍存在的屠王现象,唯独遗漏了中国.本文证实辽王朝的再生仪乃是一种反屠王仪式,同时略示屠王现象在上古中国的普遍存在,不仅填补了弗氏的空白,而且为我国古民俗研究增加了一个思考的向度.     

Spectroscopic study on the photophysical properties of chlorine substituted tetraphenylporphyrin-histidine and its zinc(Ⅱ)complexes

As the structural analogues of (bacterio)chlorophylls in photosynthetic organisms, porphyrins play an important role in building up artificial photosynthetic systems[13]. In natural photosynthetic pigment-protein complexes,certain amino acid residuals modulate the reactions ofcharge transfer and energy transfer via coordination andother types of interactions with chlorophyll molecules.For instance, in higher-plant photosynthetic reaction cen-ter PSⅡ, the oxidization-reduction system consistin…     

Chromosomal effects of adeno-associated virus vector integration.

Adeno-associated virus (AAV) vectors are currently being used in several clinical gene-therapy trials (see the NIH OBA Human Gene Transfer Clinical Trials Database); however, little is known about the chromosomal effects of vector integration. Here we report that integrated vector proviruses are associated with chromosomal deletions and other rearrangements and are frequently located on chromosome 19 (although not at the wildtype AAV integration site).

经济学视角下新闻保护调整模式析论

政府直接管制与基于市场的经济手段在新闻公共政策的调整领域都有其有利的地位,新闻政策的关键在于寻找市场调节与政府直接干预的均衡点,以达到新闻保护与经济发展协调的目的。从外部性、公共产品、信息不对称三个方面从"市场失灵"的角度分析新闻保护问题的法律调整模式,解决新闻领域的问题需要"看的见的手"和"看不见的手"兼而有之。     

Cutting tool materials for high speed machining

High speed machining (HSM) is one of the emerging cutting processes, which is machining at a speed significantly higher than the speed commonly in use on the shop floor. In the last twenty years, high speed machining has received great attentions as a technological solution for high productivity in manufacturing. This article reviews the developments of tool materials in high speed machining operations, and the properties, applications and prospective developments of tool materials in HSM are also presented.     

Submarine hot springs and the origin of life

The discovery of hydrothermal vents at oceanic ridge crests and the appreciation of their importance in the element balance of the oceans is one of the main recent advances in marine geochemistry. It is likely that vents were present in the oceans of the primitive Earth because the process of hydrothermal circulation probably began early in the Earth's history. Here we examine the popular hypothesis that life arose in these vents. This proposal, however, is based on a number of misunderstandings concerning the organic chemistry involved. An example is the suggestion that organic compounds were destroyed on the surface of the early Earth by the impact of asteroids and comets, but at the same time assuming that organic syntheses can occur in hydrothermal vents. The high temperatures in the vents would not allow synthesis of organic compounds, but would decompose them, unless the exposure time at vent temperatures was short. Even if the essential organic molecules were available in the hot hydrothermal waters, the subsequent steps of polymerization and the conversion of these polymers into the first organisms would not occur as the vent waters were quenched to the colder temperatures of the primitive oceans.
